Soil Formation

Which of the following is soil made of?

• Air, Water, Mineral, Organic Matter

• Chicken nuggets

• Water, Air

What is the bottom layer of soil called?

• Top soil

• Sub soil

• Base rock

What is the middle layer of soil called?

• Top soil

• Sub soil

• Base rock

During the "Additions" process the following happens

• Water evaporates, soil particles wash away

• Animals move the soil around

• Rainfall adds water, dust adds minerals, animal waster adds organic matter

During the "Losses" process the following happens

• Water evaporates, soil particles wash away, matter can turn into gas, minerals are taken up by plants

• Animals move the soil around

• Rainfall adds water, dust adds minerals, animal waster adds organic matter

During the "Translocations" process the following happens

• Water evaporates, soil particles wash away, matter can turn into gas, minerals are taken up by plants

• Animals move the soil around, gravity pulls water down, evaporating water draws the minerals up

• Rainfall adds water, dust adds minerals, animal waster adds organic matter

During the "Transformations" process the following happens

• Water evaporates, soil particles wash away, matter can turn into gas, minerals are taken up by plants

• Something changes into something else, humus is left when leaves decompose, weathering causes hard rock to erode

• Rainfall adds water, dust adds minerals, animal waster adds organic matter

All four processes happen at the same time

• True

• False
